KL变换消除探地雷达数据中的水平相干噪声

The Application of KL Transform to Remove Horizontal Coherent Noise in GPR Record

由于探地雷达采用共偏移距剖面的工作方式,造成数据记录中存在大量水平相干噪声。探讨了采用KL变换消除这些水平相干噪声的方法,并给出了具体的实现步骤。最后通过模型试验和实际数据验证了该方法的有效性。

Because of the common offset working mode of GPR,there are large amount of horizontal coherent noise in the GPR record.In order to remove these coherent noise,the method of KL transform are discussed and implemented in this paper?The validity of this method has been proved by applying it to the model data and the real data.
